CC-Link IE Field Network
For information on the calculation formula for transmission delay time when using CC-Link IE Field Network, refer to the
following manual.
MELSEC iQ-R CC-Link IE Field Network User's Manual (Application)
With reference to above mentioned manual, substitute the sequence scan time of the master station (SM) and the sequence
scan time of the local station (SL) with the following processing time.
SM, SL = P = R + α
• P: Processing time on a C Controller system
• R: Refresh cycle
• α: Link refresh time
It does not take time for refresh when direct access or buffer memory access is used. For information on the function
processing time, refer to the following section.

MELSECNET/H network
For information on the calculation formula for transmission delay time when using MELSECNET/H network, refer to the
following manual.
 Q Corresponding MELSECNET/H Network System Reference Manual (PLC to PLC network)
With reference to above mentioned manual, substitute the sequence scan time of the sending side (ST) and the sequence
scan time of the receiving side (SR) with the following processing time.
ST = LT, SR = LR
• LT: Refresh cycle of a C Controller module (sending side)
• LR: Refresh cycle of a C Controller module (receiving side)
